Item 250- Seal Coat

250.1 Description:

This item shall consist of a single asphalt surface treatment composed of asphalt surface treatment composed of asphalt material covered with aggregate for the purpose of sealing existing pavements in accordance with the specifications.

250.2 Materials:

A. Aggregate: Aggregates shall be of the type as shown on the plans and shall meet all the requirements of the Texas Department of Transportation (TxDOT) Item No. 302, “Aggregate for Surface Treatments” and subsequent revisions thereto. Graduation requirements when tested by TxDOT Test Method Tex-200F, Part I, shall be as shown on the plans.

B. Asphaltic Materials: Asphalt cement, emulsified asphalts, other miscellaneous asphaltic materials, and latex additives shall confirm to TXDOT Item No. 300, “Asphalt, Oils, and Emulsions” and subsequent revisions thereto.

250.3 Equipment:

A. Distributor: The distributor shall be a self-propelled pressure type, equipped with an asphaltic material heater and a distributing pump capable of pumping material at the specified rate through the distributor spray bare. The distributor spray bar shall be capable of fully circulating the asphaltic material. The distributor spray bar shall contain nipples and valves so constructed that the nipples will not become partially plugged with congealing asphaltic material, to prevent streaking or irregular distribution of asphaltic material. Distributor equipment shall include a tachometer, pressure gauges, volume measuring devices, and thermometer for reading the temperature of tank contents.

The distributor tank shall have been calibrated within three (3) years from the date it is first used on this project. The tank calibrations procedure shall be in accordance with Test Method Tex-922-K, Part I, and shall be signed and sealed by a registered professional engineer. Unless otherwise shown on the plans, the Contractor shall provide the tank calibrations and shall furnish the Engineer an accurate and satisfactory calibration record prior to beginning the work. The Engineer may at any time verify calibration accuracy in accordance with Test Method Tex-922, Part II, and may perform the recalibration if the calibration is found in error.

B. Asphaltic Spreader: A self-propelled continuous-feed aggregate spreader shall be used which will uniformly spread at the rate specified by the Engineer.

C. Rollers: Approved rolling equipment shall be of the self-propelled type and shall be designed such that a 12-ton load may be obtained by ballast loading. The roller shall be equipped with tires that will afford ground contact pressures to 90 psi or more and individual tire inflation pressures shall be within 5 psi of each other. The operation load and tire air pressure shall be within the range of manufactures chart.

D. Sweepers: A rotary, self-propelled power broom shall be acceptable for sweeping existing pavement surfaces. Vacuum sweepers or other approved equally capable equipment shall be suitable for removing loose aggregate form compacted Seal Coat.

250.4 Construction Method:

Prior to Seal Coating, all dirt and other objectionable material shall be removed from the existing pavement by sweeping of other approved methods. All existing raised pavement markings shall be removed daily, as the work progresses, and as approved by the Engineer. All vegetation found in the existing pavement shall be destroyed by an approved chemical killer. Building paper shall be placed over all manholes, valve boxes, grates, etc., to protect the surfaces from Asphaltic materials. Asphaltic materials shall not be placed, lapped, or splashed onto adjacent structures.

Seal Coat shall not be applied when the air temperature is below 60°F and if falling, but it may be applied when the air temperature is 50°F and is rising, the air temperature being taken is the shade and away from artificial heat. Seal Coat shall not be applied when the roadway surface temperature is below 60°F or when in the opinion of the Engineer, general weather conditions are not suitable. When latex modified asphalt cement is specified, Seal Coat shall not be applied when the air temperature is below 80°F and is falling, but may be applied when the air temperature is above 70°F and is rising and shall not be applied when the temperature of the surface on which the Seal Coat is to be applied is below 70°F.

Asphalt and aggregate rates as shown on the plans are for estimate purposed only and may be varied as directed by the Engineer.

The width of each application of Asphaltic material shall be such to allow uniform application and immediate covering with aggregate. The contractor shall be responsible for uniform application of asphaltic material at the junction of distributor loads. Paper or other suitable material shall be used to prevent overlapping of transverse joints.

Longitudinal joints shall match lane lines unless otherwise authorized by the Engineer.

Application of asphaltic material will be measured as necessary to determine the rate of application, in those areas where the asphalt distributor is not accessible, hand spraying may be permitted as directed by the Engineer.

Aggregate shall be immediately and uniformly applied and spread in the same width as the application of asphaltic material. The entire surface shall then be broomed or raked as required by the Engineer.

The aggregate shall be rolled for its width with a minimum of two (2) pneumatic tire rollers which shall be maintained in a good repair and operating condition. Rolling shall begin as soon as sufficient aggregate is spread to prevent pick-up and shall begin longitudinally at the outside edge of the mat and progress toward the center of the mat, uniformly lapping each preceding pass by at least 2 the width of the roller. Rolling shall continue until no more aggregate can be worked into the surface.

After all rolling, the finished surface shall be cleared of any surplus aggregate by the Contractor by sweeping. Until the work has been accepted, additional sweeping shall be required as often as necessary so that loose aggregate does not present a hazard to traffic.

The Contactor shall be responsible for the maintenance for the Seal Coat until the work is accepted by the Engineer. All holes or failures in the surface shall be repaired by use of additional asphalt and aggregate. All fat or bleeding surfaces shall cover with approved cover material in such a manner that the asphaltic material will not adhere to or be picked up by the wheels of vehicles. All parkways, private property, and driveway adjacent to the work shall be cleaned of loose aggregate and other debris as produced from Seal Coat operations.

250.5 Measurement:

Seal Coat will be measured by the square yard of completed and accepted work.

250.6 Payment:

The work performed as prescribed by this item will be paid for at the contractor unit price bid per square yard for “Seal Coat”, which price shall be full compensation for furnishing and placing all materials, sweeping, rolling, manipulations, labor, tools, equipment, and incidentals necessary to complete the work.
